5. SNMP

The Simple Network Monitoring Protocol (SNMP) is a machine to machine control and monitoring protocol .that was

developed as a means to monitor and control devices in an Internet Protocol (IP) network. SNMP has been used for many

years in computer and networking environments and is becoming popular in broadcast equipment.

Davicom Cortex units have an on-board SNMP agent that allows them to interface with external SNMP management

systems. In addition, this agent can be used to transform non-SNMP readings from legacy devices into SNMP-compatible

data that can be used by the remote SNMP management system. The Cortex’s SNMP MIB is available for download

directly from the unit under the SNMP Agent Tab in the System-IP Configuration menu.

5.1.1.

SNMP GET

The SNMP GET inputs are used to process and measure readings obtained digitally, by IP, from SNMP-enabled equipment
